CAS 644-97-3 Dichlorophenylphosphine
Overview
Dichlorophenylphosphine manufacturer (phenyldichlorophosphine; PhPCl₂; CAS 644-97-3; C₆H₅PCl₂) is a reactive aryl phosphonous dichloride used to build tertiary phosphines, phosphonium salts, and other P-containing ligands/intermediates. Supplied as a colorless to pale-yellow liquid, it is miscible with common aprotic solvents (e.g., toluene, THF, CH₂Cl₂) but insoluble in water.COA/TDS and compliant packaging from lab to bulk are available.Stock China Factory Supply
Product Description
CAS 644-97-3 Dichlorophenylphosphine
Dichlorophenylphosphine (phenyldichlorophosphine, PhPCl₂, CAS 644-97-3, C₆H₅PCl₂) is a versatile aryl P(III) chlorophosphine used to construct tertiary phosphines, phosphonium salts, and other phosphorus-containing ligands/intermediates for catalysis and fine-chemical routes. handle in dry, inert systems with appropriate base scavengers and HCl scrubbing, and follow the SDS. COA/TDS and compliant packaging from lab to bulk are available.
